Are you asking which gear ratios were available?More info. would help.

3.73 for auto, and 4.10 for manual.

That's my favorite piece of bad internet advice. Kinda like saying men wear a size 10 shoe and women wear a size 6.

There's a LOT more that goes into choosing a proper gear ratio than the type of trans.

I'll jump on the misinformation.

You probably have an 8.5 10 bolt diff.

Any more help required?

3.73s will generally be stronger than 4.10s, and you will, need to recalibrate the speedo if you want to drive it on the street as the speedo is likely tied to your odometer as well.

Depending on your power level you may also want to incorporate wheels and tires into the final drive equation with taller tires resulting in slower 60 foot times but maybe a higher trap speed. Taller tires will also generally have more sidewall area which is a factor if you decide to use a tire that wrinkles at the launch.

What is the goal of changing your gear ratio?
